RAA489255 に関するリソース
説明
The RAA489255 is a 3-cell-to-5-cell battery monitor optimized for packs with MCU control, providing battery health monitoring. It measures pack voltage, cell voltage, external temperature, and internal temperature under serial instructions from the master. System and internal checks continuously track device health and system status. The RAA489255 uses an I²C interface with cyclic redundancy check (CRC) for reliable MCU communication and provides six open‑drain high‑voltage GPIOs to drive LEDs or blow fuses.
With an average idle current of 85 µA, the RAA489255 minimizes power consumption to maximize battery storage and discharge life. The board is offered in a compact 32‑pin 4mm × 4mm QFN package for efficient integration.
